Industrial Power Supply that could be turned off by the board?

So I have read that ATX style power supplies can be turned off by the RRF. Is it possible to wire an industrial power supply that must be turned on normally, but is latched in such a way that a signal could come from the duet board to turn off the power (thus release the latch).

I know there are power relays that might be applicable, but I don't think a regular switch would be appropriate with this setup.
